Comment 19 for bug 1375252

Apologies for the tardy feedback. Many thanks to all involved, gratefully and much appreciated. From my perspective, this issue is now resolved.

I've just tried this on a freshly deployed Trusty VM in Azure - a change to the hostname with 'hostnamectl' is now preserved when the VM is rebooted.

I would like to point out though that, if not editing the /etc/hostname file directly, the 'hostnamectl' command must be used to set the hostname; using the 'hostname' command doesn't work (presumably because the hostname command doesn't change /etc/hostname).
